The Irish actor would join Tom Hanks and Emma Thompson in the movie about the making of Disney classic "Mary Poppins."

The project, with John Lee Hancock in the director’s chair, centers on the creator of Mary Poppins, P.L. Travers (Thompson). The script is said to shift back and forth between 1961 and 1907, framing Travers by her childhood in rural Queensland and her experience negotiating with Walt Disney and his team for the film of Mary Poppins.

Farrell will play Travers’ father, a banker who slowly slides into alcoholism as the family falls into financial hardship. Travers looked up to her father, and the breaking of his spirit had an effect on her writing.
